About this trial

The overall aim of the research project is to assess whether the quality of life of patients with severe eating disorders is improved by dental treatment.

Patients diagnosed with anorexia nervosa, bulimia nervosa or non-specific binge eating disorder with extensive dental treatment need will be treated with resin composite restorations or prosthetic therapy. The primary outcome measures is oral health related quality of life. Secondary are orofacial functions and oral esthetics. Patients will be compared to a waiting list.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients diagnosed with anorexia nervosa, bulimia nervosa or non-specific binge eating disorder for a minimum of 10 years = definition of a "severe" eating disorder where extensive dental damage can be anticipated to find.

Need of dental treatment of at least six teeth in one jaw,

Disqualifiers

Age <18 years or patients unable to provide informed consent.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Dental rehabilitation with either composite resin of crown therapy

    Procedure/Surgery

    Patients in group 1 will be treated with minimal invasive treatment, with restorative composite fillings. Patients in group 2 will be treated with prosthetic rehabilitation, dental crowns.

  • Waiting list

    Other intervention

Oral health related quality of life OHIP-49

OHIP-49 is a survey with 49 questions divided into 7 subgroups: Functional limitation, Physical pain, Psychologic disability, Social disability, Handicap, Orofacial Appearance and Psychosocial Impact. The categories will be graded from 0 to 4 on a Likert Scale (never = 0, seldom= 1, sometimes = 2, fairly often = 3, and very often = 4). The internal reliability, and test/retest reliability and validity of the OHIP-49 has previously been established. Since OHIP-49 measures capture both improvements and declines in oral health status, the instrument enables the possibility to conceptualize and analyze change longitudinally.

Secondary outcomes

Orofacial function (JFL-S)

JFLS is an instrument used for evaluating functional limitations. It measures mastication, vertical jaw mobility, verbal and emotional expression as well as miscellaneous functions such as swallow food and yawn. This instrument is a 20-item questionnaire which exhibits good reliability and validity and has been shown to be useful in assessing functional limitations of the jaws \[18\]. Subjects rate their jaw functional limitations on a numeric rating scale (0- 'no limitation', 10- 'extreme limita- tion'). Total score can range from 0 to 200, where 200 is the highest score which indicates extreme limitations.
